This section provides safety warnings and information on preventing electrostatic damage to the router.

Warnings

Before installing the router, read the following warnings:

---

Warning Only trained and qualified personnel should be allowed to install or replace this equipment.

---

---

Warning Read the installation instructions before you connect the system to its power source.

---

---

Warning Before working on a system that has a standby/off switch, turn off the power switch to standby and unplug the power cord.

---

---

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

---

---

Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

---

---

Warning During this procedure, wear grounding wrist straps to avoid ESD damage. Do not directly touch the backplane during with your hand or any metal tool, or you could shock yourself.

---

---

Warning Ultimate disposal of this product should be handled according to all national laws and regulations.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) is a transfer of electrostatic charge between bodies of different electrostatic potentials, such as an operator and a piece of electrical equipment. It occurs when electronic components are improperly handled, and it can damage equipment and impair electrical circuitry. Electrostatic discharge is more likely to occur with the combination of synthetic fibers and dry atmosphere.

Always follow these steps to prevent ESD when you remove and replace components:

---

Step 1 Wear an ESD-preventive wrist strap that you provide, ensuring that it makes good skin contact.

---

Caution To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively.

---

Step 2 Do not touch any exposed contact pins or connector shells of interface ports that do not have a cable attached.

If cables are connected at one end only, do not touch the exposed pins at the unconnected end of the cable.

---

Note This device is intended for use in residential and commercial environments only.

---

---

Caution Periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohms).

•Ethernet cable (yellow)

•Product documentation

To prepare for installation, follow these steps:

---

Step 1 Remove the desktop power supply, black power cord, yellow Ethernet cable, light blue console cable, and product documentation from the box.

---

Note One ADSL cable is supplied with the router; this cable was selected during the ordering process. If you have microfilters or if you do not have telephone service on the ADSL line, use the lavender CAB-ADSL-RJ11 cable. If you have a splitter installed, use the lavender CAB-ADSL-RJ11X cable with the blue stripe.

---

Step 2 Obtain the ADSL.

Step 3 Provide the terminal or PC that will be used to configure the router.

Step 4 If you plan to use the cable lock feature, provide a Kensington or equivalent locking cable.

---

Preventing Damage to the Router

When connecting devices to your router, use the color-coded cables supplied by Cisco Systems.

If you supply your own cables, see "Specifications and Cables," for cable specifications. If this appendix does not provide specifications for a particular cable, we strongly recommend ordering the cable from Cisco Systems.

Installing the Router

To install the router, perform the following tasks in order:

1. Connect the Ethernet devices to the router.

2. Connect the ADSL.

3. Connect the router to the power source.

4. Mount the router.

5. Power on the router.

6. Connect a terminal or PC to the configuration port of the router if you are troubleshooting or configuring the router by using the command-line interface (CLI).

7. Verify the router installation.

These tasks are detailed in the subsections that follow.

Connecting Ethernet Devices

Table 2-2 shows how to set the router's TO HUB/TO PC button when different Ethernet network devices are connected to the router with a straight-through cable. Table 2-2 also shows how to set the corresponding button (if any) on the network device.

Table 2-2 Connecting Ethernet Devices 

Network Device Connected to Router	Setting of TO HUB/TO PC Button	Setting of Network Device Button1
Hub with an equivalent TO HUB/TO PC button	IN	MDI (IN)
Hub with an equivalent TO HUB/TO PC button	OUT	MDI-X (OUT)
Hub without an equivalent TO HUB/TO PC button	OUT	-
PC or workstation	OUT	-

1 Network device vendors use different names for the button controlling cable selections. This table uses the Cisco 1528 Micro Hub 10/100 with an MDI/MDI-X button as an example. To determine the button name and setting for your hub, refer to your hub documentation.

Connecting an Ethernet Hub

Before connecting a hub, refer to Table 2-2 to identify the TO HUB/TO PC button settings. To connect to a hub, follow the steps in Figure 2-1.

Figure 2-1 Connecting a Hub

To verify your Ethernet connection after you have completed the router installation and have powered on both devices, check the Ethernet 1 LED on the front panel. The LED should be on. If the Ethernet 1 LED is not on, see Table 3-2 in "Troubleshooting," for troubleshooting information.

Connecting a Server, PC, or Workstation

Before connecting the server, PC, or workstation, see Table 2-2 to determine how to set the router TO HUB/TO PC button.

To connect one of these devices, follow the steps in Figure 2-2.

Figure 2-2 Connecting a Server, PC, or Workstation

To verify your Ethernet connection after you have completed the router installation and have powered on both devices, check the Ethernet 1 LED on the front panel. The LED should be on. If the Ethernet 1 LED is not on, see Table 3-2 in "Troubleshooting," for troubleshooting information.

Connecting the ADSL Line

The procedure for connecting an ADSL depends on the router, and in some cases, on your location. This section describes how to connect the ADSL cable to a wall jack.

---

Note Although the following instructions are for using a straight-through ADSL cable, they also apply to using a crossover cable for connecting your ADSL line.

Verifying the Router Installation

Use Table 2-3 to verify that you have properly installed the router.

Table 2-3 Verifying Installation 

Power/Link	LEDs to Check	Normal Patterns
Power	OK	On
To hub, server, PC, or workstation	ETHERNET 1, ETHERNET RXD, and ETHERNET TXD	•1: on when the Ethernet is physically connected and the connected device is powered on. •RXD: blinking when an Ethernet port receives an Ethernet packet. •TXD: blinking when an Ethernet port sends an Ethernet packet.

Mounting the Router

You can mount the router on either of the following surfaces:

•Table or other horizontal surface

•Wall or other vertical surface

Mounting on a Table

Do not cover or obstruct the router vents, which are located on the sides of the router.

Mounting on a Wall

You can mount the router on a wall or other vertical surface by using the molded mounting brackets on the bottom of the router and two number-six, 3/4-in. (M3.5 x 20 mm) screws. You must provide the screws. Figure 2-5 shows the mounting brackets.

---

Caution If you are mounting the router on drywall, use three hollow-wall anchors to secure the three 1/8-in. (M3) screws. If the screws are not properly anchored, the strain of the network cable connections could pull the router from the wall. Use the drill bit size that is specified by the hollow-wall anchor manufacturer.

---

Figure 2-5 Wall-Mounting Brackets (Bottom of Router)

The following conditions must be met when you mount the router:

•Because you will use the LEDs as status and problem indicators, the LEDs on the front panel must face upward and must be easily visible.

•The back panel must face downward to reduce strain on the cable connections.

•The power supply must rest on a horizontal surface such as the floor or a table. If the power supply is not supported, it could place strain on the power supply cable and cause it to disconnect from the connector on the router back panel.

To mount the router on a wall, follow the steps in Figure 2-6.
